2005 CHEVROLET KODIAK fuel pressure

If you are trying to start your engine after you have run
out of fuel, seeRunning Out of Fuel on page 5-15.
When your engine is cold, let it run for a few minutes
before you move your vehicle. This lets oil pressure
build up. Your engine will sound louder when it is cold.
Notice:If you are not in an idling vehicle and
the engine overheats, you would not be there to
see the overheated engine indication. This could
damage your vehicle. Do not let your engine
run when you are not in your vehicle.
Cold Weather Starting
If your vehicle has the DURAMAX®Diesel Engine,
the following notice applies:
Notice:Your diesel engine has an electric air intake
heater system which reduces white smoke and helps
start the engine in cold weather. Do not spray
starting uid into the air intake where it can contact
the heater elements.If you do not have the GM Automatic Ether Injection
System, do not use starting uid or you could
damage your engine. If you have the GM system,
use only GM approved starting uid that has been
tested to establish compatibility with the air inlet
heater system.
The following tips will help you get good starting in
cold weather.
•Use the recommended engine oil when the outside
temperature drops below freezing. SeeEngine Oil
(Caterpillar
®Diesel Engine) on page 5-22or
Engine Oil (DURAMAX®Diesel) on page 5-22or
Engine Oil (Gasoline Engine) on page 5-26.
When the outside temperature drops below
0°F (−18°C), use of the optional engine coolant
block heater is recommended.
•If you experience longer cranking times, notice an
unusual amount of exhaust smoke or are at
higher altitudes (over 7,000 ft. or 2 135 m), you may
use your optional engine coolant block heater.
SeeEngine Coolant Heater on page 2-24.
•SeeWhat Fuel to Use on page 5-8for information
on what fuel to use in cold weather.

If Your Diesel Engine Will Not Start
If you have run out of fuel, seeRunning Out of Fuel on
page 5-15.
If you are not out of fuel, and your engine will not start,
do this:
Turn your ignition key to RUN. Immediately after the wait
to start light goes off, turn the ignition key to START.
If the light does not go off, wait a few seconds, then try
starting your engine again. And, see your dealer as
soon as you can for a starting system check.
If the light comes on and then goes off and you know
your batteries are charged, but your engine still will not
start, your vehicle needs service.
If the light does not come on when the engine is cold,
your vehicle needs service.
If your batteries do not have enough charge to start
your engine, seeBattery on page 5-55.
Be sure you have the right oil for your engine, and that
you have changed the oil at the proper times. If you
use the wrong oil, your engine may be harder to start.Be sure you are using the proper fuel for existing
weather conditions. SeeWhat Fuel to Use on page 5-8.
If the engine starts, runs a short time, then stops,
your vehicle needs service.
{CAUTION:
Do not use gasoline or starting aids, such as
ether, in the air intake. They could damage
your engine. There could also be a re, which
could cause serious personal injury.
Engine Alarm and Automatic
Shutdown
Your check gages warning light will come on if the
system senses high engine temperature or low engine
oil pressure. If high engine temperature or low engine oil
pressure is detected, you will also hear a tone alarm
at two beats per second. The alarm and the light
will remain on until the condition is fixed. If the engine
temperature or oil pressure condition worsens, the
tone alarm will go to five beats per second.

Low Washer Fluid Warning Light
This light will come on
when your vehicle is low
on windshield washer fluid.
For more information, seeWindshield Washer Fluid on
page 5-46.
Check Gages Warning Light
This light will come on as
you’re starting the engine,
just as a check.
If this light comes on and stays on while you are driving.
it means that either your engine coolant temperature
gage or your engine oil pressure gage may be showing
a reading in the warning zone.When the check gages light comes on, you will also
hear a warning tone. The tone and the light will
stay activated until the problem is corrected.
This light may also come on if your vehicle is equipped
with the optional automatic engine shutdown system
and engine shutdown has begun. SeeEngine Alarm and
Automatic ShutdownunderStarting the Diesel Engine
on page 2-14.
Fuel Gage
Your fuel gage is located
on the right side of your
instrument panel cluster.
When the ignition is on, your fuel gage lets you know
about how much fuel you have left. When the gage first
shows empty, you’ll still have a little fuel left, but you
should get more fuel soon.

Loading Your Vehicle
There is a vehicle specific GVW Rating label on your
vehicle that shows how much weight it may properly
carry. It also shows the size of your original tires and the
inflation pressures needed to obtain the gross weight
capacity of your vehicle. This is called the Gross Vehicle
Weight Rating (GVWR).
The GVWR includes the weight of the vehicle, all
occupants, fuel and cargo.The GVW Rating label is provided by the final
manufacturer and should be on the door or door jamb.
It also tells you the maximum weights for the front
and rear axles, called Gross Axle Weight Rating
(GAWR). To find out the actual loads on your front and
rear axles, you need to go to a weigh station and
weigh your vehicle. Your dealer can help you with this.
Be sure to spread out your load equally on both
sides of the center line.
Never exceed the GVWR for your vehicle, or the GAWR
for either the front or rear axle.
And, if you do have a heavy load, you should spread
it out.

Ination - Tire Pressure
The GVW Rating label, which is on the driver’s door
frame, shows the correct inflation pressures for
your tires when they’re cold. “Cold” means your vehicle
has been sitting for at least three hours or driven no
more than 1 mile (1.6 km).
Notice:Do not let anyone tell you that
under-ination or over-ination is all right. It is not.
If your tires do not have enough air (under-ination),
you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination), you
can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazards
When to Check
Check your tires once a month or more.
Also, check the tire pressure of the spare tire
(if equipped).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Wheel Loading
Wheels are stamped with a maximum load and cold
inflation rating. Be sure you don’t exceed these. If you
ever think you need to, first contact the rim and
wheel maker to get their advice.
